Abstract

A device for feeding packaging blanks (3) to a packaging machine has a magazine with two shafts (7) mounted at the bottom for supporting the blanks (3). The shafts (7) are brought to rotate at constant speed in opposite directions to each other, hence eliminating the static friction from the bottom of the magazine. An angle is formed between the shafts (7), so that a small, forwardly directed force component contributes to the movement of the blanks (3). The dynamic friction is used to move blanks (3) towards a gate (2) at the end of the magazine, and only a small, constant feeding force (A) from a pusher is necessary for the movement.

The present invention also provides a kind of and is used for by in this casket box bottom the method that one device moves to the packaging blanks in the casket box (3) filling-packaging machine being set, wherein said device comprises at least one axle (7) that roughly extends along described packaging blanks (3) throughput direction, and axle (7) supports the packaging blanks (3) in this casket box but constant speed is arranged in this casket box bottom rotationally; This device also comprises the pusher of the packaging blanks (3) of this casket box that is used for moving; And the member that is used for packaging blanks (3) is transported to successively this wrapping machine.
Description of drawings
The present invention will further be described in detail with reference to the attached drawings, wherein:
Fig. 1 is the diagrammatic side view that is used for packaging blanks is transported to the device of wrapping machine according to the present invention, and packaging blanks is positioned in the casket box of this device, wherein expresses the distribution of the required power of packaging blanks in this device of motion;
Fig. 2 is the top schematic view of expression according to the bottom of apparatus of the present invention; And
Fig. 3 is the diagrammatic side view that is used for packaging blanks is transported to the conventional apparatus of wrapping machine, wherein expresses the distribution of the required power of packaging blanks in this device of motion.
The specific embodiment
The device that is used for packaging blanks 3 is transported to wrapping machine schematically is illustrated in Fig. 1.This device has a casket box and the doorway 2 that and a plurality of axle 7 be set in its bottom.Exercisable doorway 2 is as the backstop of this casket box exit end.Motor 4 is connected on the actuating device 5 by axle drive shaft 6.Packaging blanks 3 loads in this casket box, and wherein packaging blanks 3 is transported to this wrapping machine (not shown) and abuts doorway 2.
The top schematic view of Fig. 2 presentation graphs 1 device wherein is provided with two axles 7 in the bottom of this casket box, this axle is connected on the actuating device 5, therefore is communicated with motor 4.The length of axle 7 is corresponding with the length of this casket box.Axle 7 mutually at angle, the distance between the axle 7 is littler at 2 places, doorway of this casket box exit end, and is installed in the plane identical with this casket box bottom.
This device also comprises one when almost the reload during emptying robot (not shown) of packaging blanks 3 of casket box in the casket box; One comprise pneumatics for example in case the packaging blanks 3 that in this casket box, travels forward as shown by arrow A to the doorway 2 pusher (not shown); With 2 places are transported to packaging blanks 3 claw component of wrapping machine successively on the doorway.
At the device that is used for packaging blanks 3 is transported to wrapping machine of current use, this casket box has one by the flat bottom 1 of making of aluminium preferably of metal for example, and it has certain friction coefficient.Static friction will hinder packaging blanks 3 level and smooth and motion equably in this casket box.Another consequence of the static friction of considering be when this casket box loads recently, move these packaging blanks 3 required power must be very big, this power will reduce when this casket box comprises packaging blanks 3 less and less simultaneously, shown in arrow E among Fig. 3.The power that produces when friction coefficient slip-stick will occur during greater than carrying capacity.This phenomenon causes packaging blanks 3 to be bonded in when travelling forward on the bottom 1 of this casket box, therefore causes uneven motion, and this can hinder packaging blanks 3 is transported on this wrapping machine successively reliably.
Another factor that needs to consider is owing to there is the rebound phenomenon that increases in static friction.This phenomenon appears when the packaging blanks 3 that loads in this casket box and fold is tending towards springing back to its initial position.Carrying capacity becomes uncontrollable when packaging blanks 3 moves in this way.
Can solve described problem according to the present invention by only using dynamic friction rather than static friction.Packaging blanks 3 in this casket box be bearing in by motor 4 with constant rate of speed rotate on the opposite sense shown in Fig. 2 arrow C and the D the axle 7 on.Because this rotates also because axle 7 is not parallel, the one little force component that points to forward will help packaging blanks 3 with suspended pattern 2 motions towards the doorway, and only need the packaging blanks 3 this casket box be moved to doorway 2 from the little constant delivery power that pusher obtains shown in Fig. 1 arrow B.Because this packaging blanks has clear and definite position, implements successively this packaging blanks to be transported to by this claw component the moment of wrapping machine under constant speed safely.
